DETAILED DESCRIPTION OF THE PREFFERED EMBODIMENT

Refer from FIG. 1A to FIG. 1C, a fixing member of handheld electronics10 according to the present invention consists of a fixing seat 20, arotation axis 32 and at least one one-way rolling member 40. The fixingseat 20 is mounted with a slot 22 and the rotation axis 32 is disposedon the fixing seat 20. A stopping member 322 is set on one side of therotation axis 32 while the one-way rolling member 40 is pivoted in thefixing seat 20 by the rotation axis 32 and part of the one-way rollingmember 40 exposes outside(out of) a slot 22. The stopping member 322leans against a side wall of the one-way rolling member 40.

The one-way rolling member 40 includes a ratchet or a one-way bearing.In this embodiment, the ratchet is used. A plurality of serrated grooves402 is set inside the one-way rolling member 40. When the one-wayrolling member 40 is assembled on the rotation axis 32, the stoppingmember 322 leans against one of the serrated grooves 402. As shown infigure, the slopes of two sides of the serrated groove 402 aredifferent. One side thereof has larger slope so that resistance betweenthis side and the stopping member 322 is smaller. Thus the one-wayrolling member 40 gets easier to roll in one direction, compared withthe reverse direction. The rolling member 40 may even stop in thereverse direction. In this embodiment, the one-way rolling member 40tends to roll toward the slot 22 while gets difficult in the reversedirection. Thus when a handheld electronic 10 is set in the slot 22, theside wall of the handheld electronic 10 leans against the one-wayrolling member 40 so that the handheld electronic 10 is slipped into theslot 22 smoothly. Therefore, the handheld electronic 10 is easily setinto the slot 22 and is difficult to fall off from the slot 22.

If the one-way rolling member 40 is a one-way bearing, the one-waybearing rolls around the rotation axis 32 in a single direction when theone-way bearing is disposed on the rotation axis 32. Thus there is noneed to dispose the stopping member 322 on the rotation axis 32 forenabling the one-way rolling member 40 rolling in a single direction.Moreover, the side wall of the one-way rolling member 40 is made ofelastic material or material having larger friction (resistance). Theelastic material includes rubber. When the handheld electronic 10 is setin the slot 22, the side wall of the one-way rolling member 40 leansagainst the handheld electronic 10 and the handheld electronic 10 isclipped firmly by the elasticity of the side wall of the one-way rollingmember 40.

Refer to FIG. 2A & FIG. 2B, another embodiment is disclosed. Thisembodiment further includes an elastic arm 34 that is disposed on a sidewall of the slot 22 and a rotation axis 32 is set on the elastic arm 34.By the elastic arm 34, the one-way rolling member 40 has elasticity forclipping so that the handheld electronic 10 is mounted in the slot 22more stably. Furthermore, the size of the handheld electronic 10 mayvary and the preset distance for clipping between the one-way rollingmember 40 and the handheld electronic 10 also changes. Thus by theelastic arm 34, the handheld electronic 10 is clipped more firmly by theone-way rolling member 40. Moreover, the elastic arm 34 is disposed witha bending part 342 so that the elastic arm 34 is more flexible.

Refer to FIG. 3, a further embodiment is disclosed. The differencebetween this embodiment and above one is in that this embodiment furtherincludes a rolling member 50 and a conveyor belt 60. The rolling member50 is pivoted inside the fixing seat 20 and a part thereof exposes oninner surface of the slot 22. The rolling member 50 is on the same sideof the one-way rolling member 40 and the conveyor belt 60 is puttedaround the one-way rolling member 40 and the rolling member 50. Therolling member 50 is an idler wheel and the conveyor belt 60 is made ofrubber. When the handheld electronic 10 is set in the slot 22, theconveyor belt 60 leans against the side wall of the handheld electronic10. The one-way rolling member 40 in combination with the rolling member50 drives the conveyor belt 60 to move forward and backward and attachon side wall of the handheld electronic 10 so as to hold the handheldelectronic 10 inside the slot 22. The contact area is increased by theconveyor belt 60 and the friction force is also increased. Therefore,the handheld electronic 10 is mounted more stably.

In summary, a fixing member for handheld electronics according to thepresent invention includes a fixing seat, a rotation axis and at leastone one-way rolling member. The fixing seat is disposed with a slot andthe rotation axis is set on the fixing seat. The one-way rolling memberis pivoted in the fixing seat and part of the on-way rolling memberexposes on the surface of the slot while the one-way rolling member isset on the rotation axis. Thus a side wall of the handheld electronicleans against the one-way rolling member when a handheld electronic isset inside the slot. Therefore, the handheld electronic is mountedinside the slot easily and stably without falling off.
